It is supplied in sealed vials as a lyophilized powder for qualified laboratory use. HCG is investigated in research on reproductive endocrinology, gonadal function and related signaling pathways, and is commonly applied in cell-culture and preclinical studies. The lyophilized form provides high stability and convenient reconstitution for consistent dosing.. All lots pass strict quality verification and lot-specific certificates can be provided on request.
